lpplieation filed December 28, 1926. Serial No. 157,522."

This invention relates to new and useful improvements in tire. stripping machines particularly adapted forstrippingsolid rubber tires from their carrying rims, and has for'its primary object to substantially improve and simplify thattype of tirestripping machine shown and described in Patent No. 1,609,514, granted to me. December 7,

the machine is considerably simplified, and at the same time a smooth out is provided which is not always the case when performing the operation by the use of the machine disclosed in my prior patent.

' A further and important object is to pro vide a tire stripping machine of this character. wherein the cutting knife is mounted for swinging movement toward and away from the periphery of the tire andwherein the cutting edge of the knife blade perse is such that said cutting edge will seek the surfaceof the tire carrying rim and smooth- 1y. cut the tire from said rim surface regardless of whether or not the rim is true or warped. v I V Other objects will become apparentas the nature of the invention is better understood,

the same comprising the novel form, combination, and arrangement of parts herein after morefully described, shown in the ,accompanying drawings and claimed.

In the drawings wherein like reference characters indicate corresponding parts throughout the severalviews:

Figure 1 is a front end elevation of a tire strippin machine constructed in accordance wit the present invention, the'same being shown as actually performing a the stripping operation.

Figure 2 is a view of the knife carrying side of the machine.

Figure 3 is a top plan view thereof, and

Figure 4 is a diagrammatic view disclosing the position of the knife at the start of the stripping operation and the position that the same assumes afterthe knife has cut through the. tire and reached the rim surface. v I V Nowfhaving particular "reference to the drawings wherein there is disclosed the most practical embodiment of the invention with which I, am at this time familiar the machine consists of a substantially rectangular shaped supporting base 5 upon the top side of which at one edge is a pair of transyersely spaced vertically extending and "parallelshaft supporting standards 6 6 upon" the'standards with a relatively large worm gear 8. that has mesh with a worm 9'upon ly indicated in Figures 1 and r I 'Upon the outer end of this shaft Tis a conventional universal chuck I 11 for receive ing solid tire carrying rims of various sizes,

the rim being designated A while thesolid tiremounted thereon is designated B. c

' At the end of the base 5 opposite from the which mounted one end of a transversely extending shaft 7 that is equippedbetween v one end ofthe armature shaft of an electric -motor 10 supported upon the base 5 as cle'armotor 10' is a knife blade carrying unit'des-v ignated generallyby'the reference character 12. This unit consists of afpair of elongated and parallel spaced arms 13- -13 the lower ends'of which are, pivotally connected to 1 vertical supporting ears l b-1a formed upon the top sideof the base. 7 These arms otal connection thereof by cross brace 14 pro ect1ng rearwardly from wlnch. is an are interconnected at a po'int'above the pivoperators handle15. Extending transverse- I ly between the upper ends of the arms 13l3 and secured to the inner edges thereof is a cutting blade 16, the lower edge of which is thecutting 'edge'and which cutting edge is greatly beveled, at itsinner surface so as to layagainst the rim A after a out has been made through the tire B for prevent-V i ing' the cutting of the rim during the rota} tion of the same in the direction of the arrow in Figure 1.

In actual practice the knife blade carrying un t is swung toward the tire B until the edge of the knife blade rests against the surface of the tire as per the full lines in Figure 4, The machineis then started for rotating the tire in the direction of the arrow in Figure 1, and immediately the knife will out directly through the tire until the same has reached therim A- after which the tire [will be thoroughly stripped from the rim cut rubber tends to force the knife into .firm engagementwith the rim surface. Further-- more, owing to the pivotal connection of the cutting unit, the knife blade thereof will at all times ride against the surface of the rim even though the same may be greatly-bent with the resultthat the tire will be str pped from the rim at the surface of the rim.

In view of the foregoing description whenconsidered in conjunction with the accompanying drawings, it will atonce be apparent that I have provideda highly novel, simple, and efficient tire stripping machine that is well adapted for all the purposes heretofore des gnated, even though I have herein shown and described the invention as consisting of certain detail structural elements,j,1t is nevertheless to be understood that minor changes may be made therein 'without effecting the spirit and scope'of the appended claims. p Having thus described the invention,what 1 claim asnew is 1. In atire stripping machine of the character described, a base, a sh'aft journaled above the base, a tire ram chuck mounted upon the shaft, a knife bla-de carrying frame 1 pivoted at its lower end to the base and extending upwardly .at the side of the shaft, and a knife blade at the upper end of the frame parallel with the shaft adapted to cut through the tire upon the rim and strip the same therefrom when the shaft is rotated.

2. Ina tire stripping machine of the character described, a base, a shaft joi-rrnaled above the base, a tire rim chuck mounted upon the shaft. a knife blade carrying frame 7 pivoted at its lower-end'to the baseand ex- All tending upwardly at theside of the shaft, a knife bladeat the upper end of the frame parallel with the shaft adapted to cut through the tire upon the rim and strip the same therefrom when the shaft is rotated,

the inner surface of the blade cutting edge beingbeveled to confornrto the curvature of the rimso as to rest snugly against the rim surface during the stripping operation.

5'3. In-a tire strippingmach-ine of. the charac'ter described, a base, a shaft journaled up on the base, a tire rnn chuckmounted upon the shaft, :a knife-blade carrying frame pivoted to the base and extending upwardly at the side of the chuck and terminating above the center thereof, and a knife blade secured to the upper'end of' the frame and parallel ing-the rotation of the shaft.

5. In a'tire strippingimachine of the character described, a rotating shaft, means upon the shaft whereby a tire carrying rim may be secured thereto, and a blade parallel to the shaft pivoted in position'at one side of the shaft and arranged above the shaft and the upper side'of the tire carrying rim, said knife adapted to'bite into and strip the tire from the rim during the rotation thereof. V r

6. In a tire stripping machine of the class described, a base, a rotating shaft, means upon the shaft whereby a tire carrying rim maybe secured thereto, a blade carrying unit pivotally secured on the base adjacent said shaft, said unit including a pair of parallel spaced arins-plvotally 'securedat their lower ends on the base, a cutting blade eX-J tending transversely across the upper ends of the arms, the arms being disposed on opposite sides of thefltire earryingrim, the

cutting edge of the blade adaptedto'strip the tire from the rim during the rotation of the latter. v p
